This is a new, top quality, Namura piston and rings kit for ALL year models 2004-2007 Suzuki LT-Z250 Quadsport. Don't waste your time rebuilding your motor with cheap quality, inferior parts. Build it right the first time with this top quality kit. Namura piston and rings kits feature smooth piston heads for better fuel efficiency, hard anodized crowns making them 75% stronger than non-anodized pistons, a MOS2 Teflon/Molydbenum coating giving them high durability and lubricity, and they are made to exact OEM specifications. This kit comes complete with the piston, rings, wrist pin and circlips. It comes in different sizes, so be sure to select the correct size you need carefully. If you simply need replacement rings, we offer these as well. Also, since you're rebuilding your top end, you'll need the gaskets, which we offer. Keep in mind, if your cylinder needs machining, we offer complete machine work.
